The factory pushrods in your Cummins are designed for factory power and boost levels. As power increases, safeguard your engine with upgraded pushrods. And if you're rebuilding your engine, no time like the present for a big upgrade with a set of Manton Pushrods. These are a stock length pushrod so they'll drop in, but built from superior materials and thicker walls for increased rigidity.

WHY A THREE PIECE PUSHROD:
In simple terms, pushrods transfers energy from the lifter to the rockerarm. If a pushrod is not correctly matched to the application, incorrect valve lift and valve timing can cause engine failure. With a properly matched pushrod you will achieve maximum horsepower and ultimate valve train wear.

To achieve the proper pushrod for an engine, you must decide the pushrod length, diameter, wall thickness, materials, heat treating and end configurations to match the specific engine components and application. This may seem like a fairly easy process but to accomplish this there are several things that must be considered. This is why Manton only manufactures custom modular pushrods.

1. Each end in a pushrod must be compatible with its mating components. This requires the use of material that can function as a bearing and at the same time be as impact resistant as possible. As an additional benefit, this also allows for an unlimited amount of tip designs.
2. With a modular pushrod it allows the flexibility to choose "unique" tapers for clearance issues. Also changing the wall thickness, diameter and tapering the tube will change the natural frequency.
3. The column of the pushrod must be made out of a different material and heat treated differently than the tips. It must provide the strength to withstand the combined abuse of high engine speeds and cylinder pressure. By using a dissimilar material from the pushrod end, Manton is able to utilize any heat treat desired. In most applications, Manton uses a material that is commonly available 4130/4135 tubing.

In Manton's estimation, the only reason to ever produce a one piece pushrod would be because of the reduced cost to manufacture. But, Manton is in business to produce the highest quality pushrods available and for the reasons listed here they DO NOT manufacture one piece pushrods.
